FLASH-ELIMINATOR.

Specification of Letters Patent.

Patented Sept. 7, 1920.

Application filed June 24, 1920. Serial No. 391,385.

To all whmn it may concern:

Be it known that L'OscAR C. MoYEns, a citizen of the United States, residing at Crosbyton, in the county of Crosby and State of Texas, have invented certain new and useful Improvements in Flash-Eliminators, of which the following is a specification. reference being had tothe HOCOIHPLUIY- ing drawings.

This invention relates to flash eliminators for machine guns, rifles and the like.

An important object of the invention is to provide a device of the above character which will effectually eliminate the flash which is co-incident with the. firing of tire arms at night which allows location of a positioned weapon by the enemy.

A further object of the invention is to provide a device of this character which will simultaneously eliminate the flash of a weapon and allow the escaping gases to expand before reaching the atmosphere, thereby eliminating the major portion of the noise of the explosion.

Further objects and advantages of the invention will become apparent throughout the course of the following description.

in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure l is a longitudinal sectional view showing my device attached to the muzzle of a machine gun. I

Fig. 2 is a front elevation of my device.

Fig. 3 is a section taken on the line 33 of Fig. 1. and

Fig. 4- is a section taken on the line 4-4; thereof.

Referring now more particularly to the drawings, a suitable casing is employed preferably formed in upper and lower sections ill and ii. The upper section 10 is provided centrally thereof with a downwardly extending ribbed portion 12 upwardly concaved on its lower surface as at 12 and provided with rifling of the same pitch and size the riding of the weapon with which the apparatus is to be used. The forward end of the casing is provided with a bullet outlet opening 14 ulined with the curvature of the rib l2, and the rear end of this casing is provided with an enlarged opening l surrounding the end of the rib 12.

The attaching plate 16 is provided having a centrally threaded aperture for the reception of the threaded end 17 of the muzzle of the weapon to which the device is to be attached. The plate 16 is suitably attached to the section of the casing so that the bore of the weapon alines properly with the eoncavcd lower surfaces of the downwardly plfljtctlliii rib l2 and is preferably so arranged that the head of the forward sight of the weapon is projected above the level of the top of the section 10.

The forward or outlet end of the casing 10 is provided with a plurality of openings 19 arranged about the bullet outlet opening 13 and these openings 19 have connected therewith outlet pipes :30.

Arranged within the casing is a beveled plate 21 having its upper end disposed immediately below the cross of the projectiles passing through the casing. This beveled plate is so curved as to cause the gases of the explosion which come into contact therewith to be deflected downwardly through a gas outlet 21 formed upon the deflector plate. This outlet 21 is connected to an outlet pipe by means of a suitable coupling the pipe 23 extending through the bottom of the casing section ll and being connected with the pipes by means of a suitable coupling The coupling 2-1 is provided with an outlet 25 which may be continued. to any desired point.

Arranged within the casing sections 10 and 11 adjacent the end of the section 10, provided with the bullet outlet opening 1-1 are guides 25%. preferably four in number. being arranged in pairs upon opposite sides of the rib l3 and :u'cordingly upon opposite sides of the path of the outgo' projectile. tilidably mounted intermediate the guides 26 is a number QT having its upper surface inclined downwardly at the rear end thereof as at for a purpose presently to appear. The forward end of the member 27 is preferably so constructed that it closely engages. when in the elevated position against the groove 13 of the rib l2. and against the interior of the forward wall of the casing sci-lion l0. thereby closing the opening:- l-l. The member 27 is projected upwardly for engagement with a groove of the rib by means of suitable springs 25) engaging the under face of the member 27 and against the casing 11.

In operation, the bullet in passing through the casing section 10 engages against the inclined upper face of the member 27 moving the same downwardly against action of the springs 29 and permitting the projectile to pass out of the casing at the opening 11 i. Immediately upon passage of the projectile the springs 29 move the member :27 to the upper position again closing the aperture and preventing the flash from the aperture from following in the path of the bullet. The gases of the explosion which strike against the beveled plate 21 are deflected downwardly and pass out through the pipe 22 and the remaining gases, after expanding within the casing, pass outwardly through the outlet openings 19 and pipes 20 and roinbine with the gases from the pipe 22 at the coupling 24; and are discharged through the pipe 25.

As many changes are possible in the shape, size and general arrangement of the various parts hereinbefore described, I do not limit myself to the specific construction set forth, but may make any such changes without departing from the spirit of the invention or the scope of the subjoined claims.

Having now what I claim is:

i. In a flash eliminator for firearms, a hollow casing, provided with a vertically directed rib extending longitudinally there of, said rib having its under surface upwardly roncaved, openings formed in the ends of said casing alining with the concave lower surface of said rib, means for securing the muzzle of a firearm in alinement with one of said apertures, and a projectile deflected vertically shiftable member arranged within said casing adjacent the other of said openings to normally close the same.

'2. In a flash eliminator for firearms, a hollow casing forming an expansion chamber, provided with a vertically directed rib extending iongitudinally thereof, said rib having its under surface upwardly conraved, openings formed in the ends of said casing aiining with the concave lower surdcscribed my invention,

face of: said rib, means for securing the muzzle of a firearm in alinement with one of said apertures, a projectile deflected vertically shiftable member arranged within said casing adjacent the other of said openings to normally close the same and a baffle plate arranged within said casing and communicating with a suitable outlet.

In a flash eliminator for firearms, a hollow casing forming an expansion chamber, provided with a vertically directed rib extending longitudinally thereof, said rib having its under surface upwardly concaved, openings formed in the ends of said casing alining with the concave lower surface of said rib, means for securing the muzzle of a firearm in alincment with one of said apertures, a projectile deflected vertica ily shiftable member arranged within said casing adjacent the other of said openings to normally close the same, said casing having a plurality of other openings formed therein, conduits connected with said openings and communicating with a common discharge conduit.

4. In a flash eliminator for firearms, a hollow casing forming an expansion chamber. provided with a vertically directed rib extending longitudinally thereof, said rib having its under surface upwardly concaved, openings formed in the ends of said casin alining with the concave lower surface 0 said rib, means for securing the muzzle of a firearm in alinement with one of said apertures, a projectile deflected vertically shiftable member arranged within said casing adjacent the other of said openings to normally close the same, a baffle plate arranged within said casing adjacent said rib and provided with an outlet, a conduit connecting said outlet with a coupling, other openings formed in said casing adjacent said last named outlet, conduits connected with said outlets and with said coupling, and an outlet pipe from said coupling.

In testimony whereof I hereunto atlix my signature.
